Introduction
On behalf of Lockheed Martin Corporation (Lockheed Martin), ARCADIS of New York, Inc.
(ARCADIS) has prepared this 2011 Annual Groundwater Monitoring Report (report) for the
former Lockheed Martin French Road facility (herein, ―the site‖) in Utica, New York (see
Figure 1-1). Figure 1-1 presents a site location map. This work was completed as part of the
Corrective Measures Implementation Plan (CMIP) required by the October 3, 2008 ―Order on
Consent‖ (herein, the Order) issued by the New York State Department of Environmental
Conservation (NYSDEC) (CO6-20080321-5). The Draft Monitored Natural Attenuation Plan
(MNA Plan) (revised March 2011) is the basis for the groundwater monitoring program
presented in the sections below. Lockheed Martin recently received comments from NYSDEC
on the MNA Plan. The associated revisions do not affect designated sampling locations,
sampling frequency, or analytical parameters. As stipulated by NYSDEC, alterations to the MNA
Plan will be retained in an internal draft until more substantive changes are adopted and
NYSDEC directs that an updated version be submitted for their review. This report is organized
as follows:
Section 2—Site Description and History: Briefly describes the history and condition of the
site and previous investigations.
Section 3—Groundwater Monitoring and Sampling Program: Presents the technical approach
to the groundwater monitoring program, describes the sampling and analyses performed, and
discusses the results.
Section 4—2011 MNA Program Evaluation: Discusses and evaluates the monitored
natural-attenuation program based on sampling results from the subject site monitoring wells
(with respect to Objectives 1–4, described in section 3.2), the role of site geochemistry, and
the data-validation procedures employed.
Section 5—Summary and Conclusions: Summarizes the 2011 annual groundwater
monitoring results and discusses their implications for future site remedial efforts.
Section 6—References: Lists the references used in this report.

Section 2
Site Description and History
In the early 1950s, General Electric Company (GE) acquired approximately 55 acres of
undeveloped land on French Road in Utica, New York and built a 500,000-square-foot
manufacturing facility. (See Figure 1-1 for a site location map.) GE production operations
included manufacturing, assembling, and testing electrical components for the defense and
aerospace industries. GE production operations continued until April 1993, when the facility was
acquired by Martin Marietta Corporation (MMC).
In March 1995, MMC merged with Lockheed Corporation to form Lockheed Martin
Corporation. In March 1996, Lockheed Martin sold the property to Pinnacle Park, Inc., which
subsequently transferred the property to and leased it back from the Oneida County Industrial
Development Agency (OCIDA). ConMed Corporation (ConMed), a medical supplies
manufacturer and distributor, now occupies the facility under a lease with OCIDA. Although
Lockheed Martin no longer owns the property, the corporation retains responsibility for
environmental cleanup related to past releases at the site. Figure 2-1 presents a facility map.
Groundwater beneath the northeast portion of the main manufacturing building (known as the
Solvent Dock Area) and in an area along the Former Northern Perimeter Ditch (FNPD) has been
adversely affected by volatile organic compounds (VOCs). The former Solvent Dock and
immediate vicinity (referred to hereafter as the Solvent Dock Area) once included a 275-gallon
fiberglass overflow-retention tank. This tank stored spent waste solvents, which were
periodically sampled, pumped from the tank, and disposed of by waste haulers. The tank was
removed in June 1990, at which time the tank was observed as dented and leaking fluid. The
FNPD (running along the northern property boundary) was an open-drainage swale that received
storm water from the area north of the manufacturing building and conveyed the water, along
with storm water from the western portion of the property, to a manhole before discharging it to
the municipal storm sewer.
2011 ANNUAL GROUNDWATER MONITORING REPORT • FORMER FRENCH ROAD FACILITY, UTICA, NEW YORK PAGE 2-2 Utica 2011 Annual GWM Report (v4)
GE, MMC, and Lockheed Martin have investigated groundwater in these areas since 1991. In
November 1994, Blasland, Bouck, & Lee, Inc. (BBL) investigated the facility storm sewer in the
Solvent Dock Area. That investigation determined that VOCs detected in the storm sewer are
attributable to the discharge of VOC-contaminated groundwater into the FNPD and infiltration of
VOC-contaminated groundwater from the Solvent Dock Area into the storm sewer beneath the
building.
In May 1995, BBL completed a Storm Sewer Investigation Report (BBL, 1995a), which
recommended that the contaminated portion of the storm sewer flow be collected, treated, and
discharged to meet proposed ―State Pollutant Discharge Elimination System‖ (SPDES)
VOC-effluent limitations. BBL evaluated remedial design alternatives (in accordance with
NYSDEC recommendations) that would remedy contaminated groundwater by addressing the
source of VOCs entering the storm sewer. The results of this evaluation are in the Storm Sewer
Basis of Design Report (BBL, 1995d).
BBL completed the final design of the French Road facility groundwater collection and treatment
system (GCTS) in October 1995. System construction was completed in June 1996 as an interim
corrective measure (ICM). It collects groundwater from the Solvent Dock Area and the FNPD
area via two under-drains, conveys the collected groundwater to a treatment building where a
low profile air stripper removes the VOCs, and the treated effluent is then discharged to the
municipal storm water system.
Once the system was installed and the ditch was replaced by a 24-inch-diameter high-density
polyethylene (HDPE) pipe, groundwater no longer discharged into the northern perimeter ditch.
The pipe now conveys storm water that formerly flowed in the ditch. The ditch area was filled and
contoured to match the existing grade. The GCTS was expanded in 2010 to include a third
collection line running through the facility’s eastern parking lot, parallel to a storm sewer running
east–west toward a common storm sewer line (with eventual discharge to Nail Creek). This work
also upgraded several GCTS components, notably the air stripper and associated controls.
BBL subsequently developed a hydraulic- and chemical-oriented groundwater-monitoring
program to evaluate the effectiveness of the GCTS for the Solvent Dock Area. This program, as
presented in the Ground-Water Sampling and Analysis Work Plan (BBL, 1998), has been
modified through monthly and quarterly correspondence with NYSDEC to accommodate
2011 ANNUAL GROUNDWATER MONITORING REPORT • FORMER FRENCH ROAD FACILITY, UTICA, NEW YORK PAGE 2-3 Utica 2011 Annual GWM Report (v4)
changing conditions over the project life. In response to observed groundwater contamination at
the site (as described above), Lockheed Martin voluntarily installed and operated the GCTS and
began an investigation of soil vapor and indoor air quality.
The results of several soil-vapor and indoor-air quality studies led to the installation (in
July 2008) of a sub-slab depressurization system (SSDS) in the northeast portion of the facility’s
main industrial building as an interim corrective measure (ICM). The ICM is designed to
mitigate elevated chlorinated-VOC vapors detected below the concrete slab of the building. Soil
vapors extracted from the subsurface are treated by carbon filtering before being discharged to
the atmosphere. This minimizes the potential migration of VOCs from sub-slab soil-vapor to air
inside the main building where workers are often present. This system was expanded in 2010 in
response to continued investigation and evaluation of the system’s performance.
Lockheed Martin’s investigations into the area of concern identified at the site were completed as
part of the Corrective Measures Study (CMS) and presented in the Corrective Measures Study
Report (CMS Report, ARCADIS, 2009). The CMS Report selected monitored natural attenuation
(MNA) as one of the remedial technologies for the corrective measures alternative to site address
groundwater contamination, but Lockheed Martin deemed that supplemental investigations into
specific areas of the site were warranted, to fully characterize the extent of contamination and to
confirm the effectiveness of the remedial actions recommended in the CMS Report. An initial
supplemental investigation was completed in late 2009, with a second investigation in 2010.
These investigations are summarized in the Former Northern Perimeter Ditch Supplemental
Investigation Report (FNPD SIR, ARCADIS, 2011), which confirmed the presence of
VOC-contaminated groundwater near the FNPD and recommended further investigation of
contaminants in soil, groundwater, and soil-vapor, as well as improved characterization of
groundwater flow and water table elevations.
The data presented in both the FNPD SIR and the CMS Report has been the basis for identifying
and evaluating potential remedial technologies for the FNPD area. A Feasibility Study Report
(ARCADIS, 2011) for the FNPD was submitted to NYSDEC in June 2011. It selected a
combination of in situ biological treatment, continued operation of the GCTS, implementation of
institutional controls, and conduct of MNA as the most feasible remedial alternative for the
2011 ANNUAL GROUNDWATER MONITORING REPORT • FORMER FRENCH ROAD FACILITY, UTICA, NEW YORK PAGE 2-4 Utica 2011 Annual GWM Report (v4)
FNPD. A work plan for a pre-design investigation at the FNPD, appended to the FS Report, is
aimed at filling remaining data gaps from the FNPD SIR.
The work plan also calls for a bioremediation pilot-test. The New York State Department of
Environmental Conservation (NYSDEC) has approved the work plan and will review the FS
Report, contingent on the pilot-test results. The work plan is now being implemented, with the
pilot test planned for spring 2012. Historical data generated as part of the activities referenced
above are in Appendices A–C. Appendix A presents data collected from 1996–2008; Appendix B
presents data collected from 2008–2009; and Appendix C presents data collected in 2010.
2.1 REMEDIAL ACTION OBJECTIVES
The goal of the MNA system is to (while regularly monitoring) allow natural processes to reduce
concentrations of constituents of concern (COC) in groundwater until NYSDEC
groundwater-quality standards have been achieved, thereby better protecting human health and
the environment. The remedial action objectives (RAOs) for the system designed to implement
MNA at the French Road facility are as follows:
demonstrate that COC concentrations in site groundwater are not a significant risk to human health or the environment;
prevent migration of contaminants in groundwater at concentrations above cleanup goals; and
prevent off-site migration of COC in groundwater at concentrations exceeding cleanup goals.
The MNA system described below achieves these objectives through natural attenuation.
2.2 DESCRIPTION OF TREATMENT TECHNOLOGY
MNA (as defined by the United States Environmental Protection Agency [USEPA] in Office of
Solid Waste and Emergency Response ―Directive 9200.4-17P‖ [1999]) refers to the reliance on
natural attenuation processes to achieve site-specific remedial objectives within a reasonable
period (as compared to other methods). Under favorable conditions, these natural attenuation
processes (e.g., biodegradation, dispersion, dilution, sorption, volatilization, chemical or
biological stabilization, transformation, or destruction of contaminants) act without human
intervention to reduce the mass, toxicity, mobility, volume, or concentrations of contaminants in
2011 ANNUAL GROUNDWATER MONITORING REPORT • FORMER FRENCH ROAD FACILITY, UTICA, NEW YORK PAGE 2-5 Utica 2011 Annual GWM Report (v4)
soil and groundwater. The time required for these processes to reduce contaminant
concentrations to levels that protect human health and the environment varies widely among
different hydrogeologic systems and different chemical contaminants, and depends on the
quantity of contaminant released.
In general, MNA is an appropriate remediation method only where its use would protect human
health and the environment and where it can achieve site-specific remediation objectives within a
reasonable period (as compared to other alternatives). When relying on natural attenuation
processes for site remediation, USEPA prefers processes that degrade or destroy contaminants.
USEPA recognizes MNA as complementary to other remediation technologies (e.g., source
control). USEPA generally expects that MNA will be appropriate only for sites with a low
potential for contaminant migration (USEPA, 1999).
MNA can involve various natural processes, including:
Biodegradation—Changing the form of compounds by means of living creatures, such as microorganisms. Under optimal conditions, microorganisms can produce or encourage
chemical reactions that change contaminants into a form(s) posing little or no health risk.
Dispersion and dilution—As dissolved contaminants move farther from the source area, they disperse and are diluted to progressively lower concentrations over time.
Contaminant concentrations eventually may be reduced sufficiently so that risk to human
and environmental health is minimal.
Sorption—Contaminant molecules dissolved in groundwater moving through soil and sediment particles (e.g., sand, silt, clay, organic matter) can sorb (i.e., adhere) onto these
particle surfaces and hold bulk liquids in the pores in and between the particles, thereby
slowing or stopping contaminant migration.
Chemical reactions—Some contaminants, such as trichloroethane, can undergo significant degradation by chemical reactions without microbial activity. Recent research
has shown that enhanced tetrachloroethene (PCE)- and dichloroethene
(DCE)-degradation reactions can occur by alternative, abiotic mechanisms, proceeding to
different chemical products. In particular, a variety of iron- and sulfur-bearing mineral
species participate in degradation reactions with chlorinated ethenes at the mineral/water
interface. Abiotic-reaction conditions favor transformation of chlorinated ethenes by
dichloroelimination rather than by sequential hydrogenolysis (Suthersan, 2005).
Volatilization—Many organic contaminants (e.g., petroleum hydrocarbons and chlorinated solvents) evaporate readily into the atmosphere, where air currents disperse
the contaminants, thus reducing concentrations in groundwater.
2011 ANNUAL GROUNDWATER MONITORING REPORT • FORMER FRENCH ROAD FACILITY, UTICA, NEW YORK PAGE 2-6 Utica 2011 Annual GWM Report (v4)
Groundwater cleanup goals for the site are the NYSDEC Technical Operational and Guidance
Series (TOGS) 1.1.1 Ambient Water Quality Standards and Guidance Values (NYSDEC, 1998).
Remedial criteria for site groundwater (per the Order) stipulate that groundwater contaminants
will no longer pose a threat to human health or the environment.
Site conditions meet the criteria for MNA because:
contaminants in groundwater can potentially be remedied by natural attenuation-processes;
the contaminant plume appears stable, with a low probability that environmental conditions influencing plume stability will change over time;
human health, drinking water supplies, other groundwater, surface water, ecosystems, sediments, air, or other resources would not be adversely affected as a consequence of
selecting MNA as the remediation option; little or no demand is projected for the affected
groundwater over the period during which the remedy would remain in effect;
the contamination would not exert a long-term detrimental effect on available water supplies or other environmental resources;
the estimated remediation period is regulatorily acceptable;
no continuing source of contamination exists; and
reliable site-specific mechanisms for implementing institutional controls are available.
As selected in the CMS Report, the major components of the selected corrective-measures
alternative for site groundwater include MNA, operation and maintenance of the existing GCTS,
and institutional controls. As noted, in situ bioremediation has also been selected for the FNPD.
This is subject to the results of a pilot test and NYSDEC’s review of the FNPD Feasibility Study
Report.
2.3 GROUNDWATER CONTAMINANT DISTRIBUTION
Groundwater under the northeast portion of the main manufacturing building and the FNPD has
been contaminated by VOCs, including tetrachloroethene (PCE), trichloroethene (TCE),
cis-1,2-dichloroethene (cis-1,2-DCE), and vinyl chloride. These constituents, as well as
trans-1,2-dichloroethene (trans-1,2-DCE) and 1,1-dichloroethane (1,1-DCA), generally define
the COC for the site MNA program. Depth to groundwater in these areas is shallow and ranges
from two to seven feet below ground surface (ft bgs). The source of the groundwater
2011 ANNUAL GROUNDWATER MONITORING REPORT • FORMER FRENCH ROAD FACILITY, UTICA, NEW YORK PAGE 2-7 Utica 2011 Annual GWM Report (v4)
contamination under the northeast portion of the main building is probably the former 275-gallon
overflow-retention tank, which was located immediately north of the loading dock along the
northern wall of the manufacturing building. This tank was removed in 1990 as part of an interim
remedial measure. Reports indicate that the overflow-retention tank was in poor condition and
leaking upon removal.
As part of the tank removal, approximately five cubic yards of contaminated soil were removed
for off-site disposal. Analytical data for soil samples collected near where the tank was removed
indicate no remaining soil contamination. Residual on-site dissolved-phase constituents in
groundwater are believed to result from isolated releases that affected both soil and groundwater.
The inverts (bottom) of former underground-storage tanks were likely near or below the water
table.
Soil, groundwater, and surface-water samples collected at the FNPD during initial and
supplemental CMS investigations did not identify a specific source of observed groundwater
contamination, but did identify areas of higher relative impacts that may be contributing to the
continued detections of VOCs in groundwater along the FNPD. These areas are at the western
and eastern ends of the maintenance building and may be due to localized disposal during past
facility operations.
Groundwater contamination is found primarily in fill and shallow till. The water table is
encountered near the bottom of the fill, typically within one foot of contact with the underlying
till. Groundwater contamination is observed primarily in wells screened either solely within the
fill or within the fill and underlying till. Hydropunch data collected from several vertical
intervals within the till indicate decreased contamination with depth. Grain-size analysis and
hydraulic-conductivity testing show that the fill and till both have a very low capacity to transmit
water; that is, the fill and till exhibit very low permeability. This has naturally ―contained‖ the
migration of contaminated groundwater within the northeastern portion of the site. Off-site
migration of contaminated groundwater has not been observed.

Section 3
Groundwater Monitoring and Sampling Program
To achieve the site remedial action objective (RAO), the MNA Plan specifies monitoring
parameters, sampling frequency, and sampling locations for the site monitoring program.
3.1 MONITORING PARAMETERS
Groundwater VOCs comprise the parameters being monitored at the site (USEPA Method 8260).
Measurement of field parameters depends on the sampling method used at individual sampling
locations. Most sampling locations were purged and sampled using dedicated bailers. At these
locations, field parameters consisted of pH, dissolved oxygen (DO), conductivity, temperature,
and water levels. DO at these locations was not measured from bailer samples but was instead
measured using a down-hole sensor.
Three monitoring wells (MW-1, MW-3, and MW-10) were sampled via low-flow purging and
sampling procedures. For these wells, reduction-oxidation (redox) potential was also recorded
using low-flow techniques. Selected points were also monitored for additional parameters,
including ferrous iron (via a field kit), nitrate, sulfate, total alkalinity, and methane. As specified
in the MNA Plan, these MNA parameters will be monitored quarterly for one year. After four
quarters, only VOCs and field parameters (as described above) will be monitored. We assume
that these parameters will provide sufficient information to evaluate natural attenuation
mechanisms. Sampling protocols and standard operating procedures are included as
Attachment 2 of the site-specific Quality Assurance Project Plan (ARCADIS, 2009).
3.2 MONITORING LOCATIONS
The well network for MNA monitoring at the site is presented in Table 3-1 and shown in
Figure 3-1. Existing wells were selected as VOC monitoring points based on the current and
anticipated extent of contaminants in groundwater (and as presented in the CMS Report and
2011 ANNUAL GROUNDWATER MONITORING REPORT • FORMER FRENCH ROAD FACILITY, UTICA, NEW YORK PAGE 3-2 Utica 2011 Annual GWM Report (v4)
supporting documents). Monitoring wells were selected for annual, semi-annual, or quarterly
sampling. Monitoring wells selected for sampling, their corresponding sampling frequencies, and
sampling rationales are as follows:
MW-1 (quarterly) is within the plume and typically exhibits elevated VOC concentrations;
MW-2 (annually) is within the plume and typically exhibits elevated VOC concentrations;
MW-3 (quarterly) is within the plume and typically exhibits elevated VOC concentrations;
MW-4 (annually) is at the fringe of the plume and hydraulically upgradient;
MW-5 (semi-annually) is at the fringe of the plume and hydraulically upgradient;
MW-10 (annually) is at the fringe of the plume and hydraulically cross-gradient;
MW-13S (quarterly) is at the fringe of the plume, hydraulically upgradient, and monitors the shallow undifferentiated-fill unit;
MW-14BR (annually) is downgradient of the plume and monitors the bedrock unit;
PZ-5 (quarterly) is within the plume and typically exhibits elevated VOC concentrations;
PZ-6 (semi-annually) is within the plume and typically exhibits elevated VOC concentrations;
PZ-7 (semi-annually) is near the downgradient extent of the plume and typically does not exhibit elevated VOC concentrations;
PZ-8 (quarterly) is within the plume and typically exhibits measurable VOC concentrations;
PZ-11R and PZ-13R (quarterly) are at the edge of the plume and typically exhibit elevated VOC concentrations;
PZ-18 (annually) is at the fringe of the plume, hydraulically cross-gradient, and monitors groundwater quality at the eastern extent of the site;
PZ-26 (annually) is upgradient of the plume and monitors groundwater quality at the northern extent of the site;
A1-PZ-2 (quarterly) is at the fringe of the plume and monitors groundwater quality at the western extent of the FNPD impacts;

A2-PZ-1 (quarterly) is within the FNPD plume and exhibits measurable VOC concentrations; and
A2-PZ-7 (semi-annually) is within the FNPD plume and exhibits measurable VOC concentrations.
As identified in Table 3-1, groundwater-elevation measurements were collected before
groundwater sampling at all accessible site monitoring-wells. Groundwater-elevation
measurements are in Table 3-2 and Figure 3-2. Table 3-3 shows the construction details of
monitoring wells and piezometers.
Monitoring wells selected for the MNA monitoring program will ensure that the site RAOs are
being achieved. The following subsections outline the objectives of the MNA network wells:
Objective 1—Verify that contaminant concentrations are decreasing with time such that
cleanup goals will be met. This objective will be met by monitoring those wells where
exceedances have been reported. Long-term trend analysis will confirm downward trends in
contaminant concentration, and MNA performance will be gauged against this analysis. At no
point during the MNA period are contaminant concentrations expected to exceed historical
maximums. Table 3-1 includes Objective 1 monitoring locations.
Objective 2—Confirm that contamination is not spreading to uncontaminated areas.
Contaminants are expected to continue to disperse within known preferential-flow paths
throughout the duration of the remedy. This objective will be met by monitoring those wells
spanning the site (laterally and vertically) that yield concentrations below cleanup goals.
Contamination in these locations is expected to be detectable but below cleanup goals or
below detection limits. Table 3-1 includes Objective 2 monitoring locations.
Objective 3—Monitor contaminant levels at potential exposure points under current land use
conditions. The monitoring well network will monitor contaminant levels at the site to ensure
that proper personal protective equipment is used, should subsurface work be done in an area
with contaminant levels exceeding cleanup goals. Wells selected for this objective are in
locations that would cover potential areas of subsurface work, including both interior and
exterior areas. Table 3-1 presents Objective 3 monitoring locations.
2011 ANNUAL GROUNDWATER MONITORING REPORT • FORMER FRENCH ROAD FACILITY, UTICA, NEW YORK PAGE 3-4 Utica 2011 Annual GWM Report (v4)
Objective 4—Monitor site hydrologic conditions over time to identify any changes in
groundwater flow that might compromise human health or the environment. This includes
evaluating groundwater elevations in both the overburden and bedrock monitoring wells.
Monitoring wells that support this objective span the site (laterally and vertically) and will
detect changes in groundwater flow and contaminant migration. All site monitoring well
locations will be monitored quarterly for groundwater elevations, and will therefore be
included as Objective 4 locations.
The four objectives listed above aim to verify that contaminant concentrations are not a
significant risk to human health or the environment, to monitor the migration of contaminants at
the site, and to monitor the hydrogeologic nature of the site to detect changes for use in future
environmental decision-making. Monitoring locations at the site have been mapped to primary
objectives, but various monitoring locations will be used for all objectives during data analysis
and interpretation. Table 3-4 presents each of the monitoring locations and their primary
objective.

Section 4
2011 MNA Program Evaluation
4.1 PROGRAM INTRODUCTION
The MNA Plan (ARCADIS, 2011) calls for quarterly, semi-annual, and annual monitoring to
evaluate the performance of the MNA remedy. The first groundwater-sampling event as part of
the MNA plan was conducted on September 26–28, 2011. It constitutes the annual event
for 2011. Results of the September 2011 sampling for wells and piezometers are summarized in
Appendix D; selected constituents are plotted spatially in Figure 4-1; selected constituents are
further summarized according to Objective-monitoring locations in Table 4-1. Laboratory
analytical results for September 2011 groundwater monitoring are in Appendix E. Historical
chemical-analytical results of groundwater samples collected from piezometers and monitoring
wells are summarized in Appendices A through C. Appendix A presents data collected from
1996–2008, Appendix B presents data collected from 2008–2009, and Appendix C presents data
collected in 2010.
As prescribed in the MNA Plan, evaluation of data for each of the four objectives will be
conducted after each sampling event. The evaluation of the single sampling event conducted
in 2011 is presented in the following sections. The limited historical data set for several
monitoring points (most monitoring points are newly installed) means that the statistical
evaluation defined in the MNA Plan cannot be applied to all locations until more data are
collected as part of ongoing monitoring. Nonetheless, for those qualifying locations, available
historical data that were evaluated against recent results (in accordance with the MNA Plan) and
conclusions and recommendations are presented, where appropriate.
2011 ANNUAL GROUNDWATER MONITORING REPORT • FORMER FRENCH ROAD FACILITY, UTICA, NEW YORK PAGE 4-2 Utica 2011 Annual GWM Report (v4)
4.2 OBJECTIVE 1 WELL EVALUATIONS AND RESULTS
Groundwater quality from Objective 1 monitoring locations was assessed by comparing the
analytical results to the NYSDEC TOGS 1.1.1 ―Ambient Water Quality Standards and Guidance
Values‖ (SGVs, Table 4-1). Chlorinated VOCs are among the predominant constituents detected
at concentrations greater than SGVs. In addition, 1,1,2-trichloro-1,2,2-trifluoroethane exceeded
the SGV at sampling location A2-PZ-1. Non-aqueous-phase liquids were not detected in any
wells during the well-gauging event. Constituents detected at the site are similar to those
previously identified. However, detected concentrations of constituents at piezometer A2-PZ-1
are greater than those reported historically at the site.
Long-term trend analysis of analytical results from Objective 1 wells evaluated whether an
unexpected expansion of a contaminated area or a sustained increase in constituent of concern
(COC) concentrations in the area of known contamination has occurred. Recent data were also
compared against historical maximums. The eight most recent sampling results for a given well
and any COC detected were used to complete the trend analysis. Samples included in this
analysis were collected through September 2011.
The requirements for historical data limited statistical analysis to sampling locations MW-1,
MW-3, and PZ-5. This is because other locations that were more recently installed and/or are less
frequently sampled lack the requisite eight or more data points. Only one or two data points are
currently available for monitoring locations PZ-8, PZ-11R, PZ-13R, A1-PZ-2, A2-PZ-1, and
A2-PZ-7; PZ-6 only has four points. The results from these statistical tests were used in
conjunction with the performance-monitoring decision tree to select response actions for further
evaluation. The site-wide performance-monitoring decision tree for Objective 1 sampling
locations is in Figure 4-2.
The decision tree provides a common process for evaluating statistical results and triggering a
response action (when necessary) to ensure remedy effectiveness. The performance-monitoring
well network monitors long-term trends in recognized areas of contamination, based on the
objectives of the MNA Plan. Persistent, increasing trends and/or a sudden increase in individual
COC concentrations may signify unexpected changes in the plume and therefore initiate a
response action within the decision tree. The three results of statistical analyses that trigger
2011 ANNUAL GROUNDWATER MONITORING REPORT • FORMER FRENCH ROAD FACILITY, UTICA, NEW YORK PAGE 4-3 Utica 2011 Annual GWM Report (v4)
action are (1) a statistically increasing trend, (2) a sudden increase, and (3) exceedance of a
historical maximum paired with an increasing trend.
The initial step of the overall trend analysis is to screen COC concentrations found in Objective 1
wells against their respective cleanup goals. If the eight most recent results for a specific COC at
a monitoring well were less than its respective cleanup goal, the COC trend result for that
particular well was not calculated. If any of the eight most recent results for a specific COC at
Objective 1 wells were equal to or greater than the respective cleanup goals, then a statistical-
trend method using the non-parametric Mann-Kendall test was employed. A pre-statistical test
evaluation was also included to develop concentration/time plots of data from a given well,
which can identify temporal patterns in the data, such as periodic fluctuations (e.g., seasonality),
or an overall trend in the data (e.g., increasing, decreasing, or stable).
The statistics for the Mann-Kendall test were calculated on a spreadsheet following USEPA
(2006) guidance. The Mann-Kendall trend test is a non-parametric test that evaluates trends
based on ranked concentration-data, rather than individual concentration-values. Mann-Kendall
trend tests were conducted to evaluate concentration trends without the potential confounding
effects of large variations in concentrations over time at a given location. A series of pair-wise
slopes were calculated to determine the change in the concentration divided by the time interval
between sequential sampling events. A test-statistic ―S‖ was computed based on the difference
between the number of pair-wise slopes that are strictly positive differences and negative
differences. The null hypothesis of no trend (equal numbers of positive and negative differences)
was evaluated at a 90% confidence interval.
The p-value of the correlation provides a measure of the level of significance of the statistical
test. Correlations were accepted as significant for p-values less than or equal to 0.1 (significant
trend identified at the 90% confidence level) and not significant for p-values greater than 0.1 (no
significant trend identified at the 90% confidence level,). The trend direction was defined based
on review of concentration/time plots of data from a given location. Trend direction was defined
as decreasing if concentrations indicated a significant decreasing trend over time, or increasing if
concentrations indicated a significant increasing trend over time.
Where non-detect concentrations were used in computations, the concentrations were assumed to
be one-half of the detection limits. Use of this value for concentrations that were below detection
2011 ANNUAL GROUNDWATER MONITORING REPORT • FORMER FRENCH ROAD FACILITY, UTICA, NEW YORK PAGE 4-4 Utica 2011 Annual GWM Report (v4)
provides a conservative estimate for evaluating concentration trends over time. Wells with
greater than 50% non-detects were not included in the analysis.
The term sudden increase identifies an unexpected increase in COC concentrations. Evaluation
of monitoring data identified sudden increases that may have occurred after implementation of
the MNA remedy. The most recent eight samples were used to calculate a COC-specific mean
and standard deviation. A result exceeding the mean plus three standard deviations was
considered a sudden increase. The most recent concentration of a given COC in a well was
compared to this threshold to determine whether a sudden increase had occurred. An exceedance
of a historical maximum is a term used in the Objective 1 decision tree and defined as any value
exceeding the maximum concentration of the historical data set. After each sampling event, the
concentrations of COC detected were compared with their respective historical maximums for
each location.
The results of the Mann-Kendall analysis, including interpretation of trend directions and
p-values of the test at the 90% confidence level, are summarized in Table 4-2. Results of the
sudden increase evaluation for the selected Objective 1 wells are presented alongside the trend
analysis in Table 4-2. The table also presents historical maximums for statistically qualified
locations. Trend directions listed in Table 4-2 are summarized from the review of
concentration/time plots presented as Figures 4-3a through 4-3f.
As shown in Table 4-2, no increasing trends were identified for Objective 1 locations MW-1,
MW-3, and PZ-5. All identified trends from Mann-Kendall analysis were determined to be
decreasing based on review of respective concentration/time plots. No sudden increases or
historical maximum exceedances were identified. As noted, statistical results of monitoring data
from sampling locations MW-1, MW-3, and PZ-5 are subject to processes defined in the
performance-monitoring decision tree shown in Figure 4-2. The respective sampling locations
are subject only to continued monitoring (as provided for in the decision tree) because these
results do not identify increasing trends, sudden increases, or exceeded maximums.
4.3 OBJECTIVE 2 WELL EVALUATIONS AND RESULTS
The Objective 2 monitoring wells are intended to confirm that contamination is not spreading to
uncontaminated areas of the site. Objective 2 monitoring wells consist of MW-5, MW-13S,
2011 ANNUAL GROUNDWATER MONITORING REPORT • FORMER FRENCH ROAD FACILITY, UTICA, NEW YORK PAGE 4-5 Utica 2011 Annual GWM Report (v4)
MW-14BR, PZ-18, and PZ-26. Results from these wells are summarized and compared to
cleanup goals in Table 4-1. These results are also plotted spatially on a facility plan in Figure 4-1.
Data from the September 2011 sampling show that all COC in these wells are below cleanup
goals for the site, and most of these COC are below their detection limits (Table 4-1). Results of
Objective 2 monitoring wells therefore indicate that contamination is not spreading to
uncontaminated areas of the site.
4.4 OBJECTIVE 3 WELL EVALUATIONS AND RESULTS
The Objective 3 monitoring wells defined in the MNA plan monitor contaminant levels at
potential exposure points under current land use conditions. The monitoring well network will
monitor contaminant levels at the site to ensure that proper personal protective equipment is
used, should subsurface work be done in an area with contaminant levels exceeding cleanup
goals. Wells selected for this objective are in locations that would be potential areas of
subsurface work, including both interior and exterior areas. Sampling results from
September 2011 are summarized in Table 4-1 and shown in Figure 4-1.
All COC in Objective 3 wells MW-4 and PZ-7 are below their respective cleanup goals
(Table 4-1). For Objective 3 well MW-2, only cis-1,2-DCE, vinyl chloride, and
1,1-dichloroethane (1,1-DCA) remained above cleanup goals in the September 2011 sampling.
For Objective 3 well MW-10, only cis-1,2-DCE and vinyl chloride are above cleanup goals. All
other COC are below cleanup goals. When subsurface work is done in the area of MW-2 and
MW-10, proper personal protective equipment should be used.
4.5 OBJECTIVE 4 WELL EVALUATIONS AND RESULTS
Objective 4 monitoring wells defined in the MNA Plan monitor hydrologic conditions at the site
over time to identify any changes in groundwater flow that might alter the basis of the
assumptions used to create the MNA Plan. This includes evaluating groundwater elevations in
both the overburden and bedrock monitoring wells. Monitoring wells that support this objective
span the site (laterally and vertically) and will detect changes in groundwater flow and the
direction of potential contaminant migration. All on-site monitoring wells are monitored
quarterly for groundwater elevations and are included as Objective 4 locations. Groundwater-
elevation data from the September 2011 sampling event are summarized in Table 3-2 and shown
2011 ANNUAL GROUNDWATER MONITORING REPORT • FORMER FRENCH ROAD FACILITY, UTICA, NEW YORK PAGE 4-6 Utica 2011 Annual GWM Report (v4)
in Figure 3-2. The elevation data indicate that groundwater is flowing to the southeast, which is
consistent with historical observations.
4.6 SITE GEOCHEMISTRY EVALUATION
Field parameters consisting of pH, dissolved oxygen (DO), oxidation-reduction potential (ORP),
specific conductivity, and temperature are periodically collected to evaluate potential natural-
attenuation mechanisms at the site. Additional geochemical parameters, including ferrous iron
(via a field kit), nitrate, sulfate, total alkalinity, and methane, are also periodically collected at
selected locations. These data provide information on geochemical conditions, which help assess
whether natural attenuation is occurring.
Geochemistry results for the September 2011 sampling are summarized below. Table 4-3
provides the field parameters and geochemical parameters for all monitoring locations sampled
in September 2011:
The pH measured was in the neutral range (6.7–7.8), except for well MW-14BR (pH of 9.7), which is at the edge of the southeastern corner of the site. This relatively higher pH
at well MW-14BR is consistent with previous pH measurements at that location.
Nitrate concentrations were low. Nitrate concentrations measured at most of the locations were near or below the detection limit, except for MW-1 (0.73 milligrams per liter
[mg/L]).
DO values were detected in nearly all of the wells at concentrations ranging from 0.04–1.9 mg/L. Only A2-PZ-7 had a higher DO (4.5 mg/L).
Sulfate concentrations were measured at selected locations and range from below the detection limit to 166 mg/L. However, only one of these locations (A1-PZ-2) indicates a
sulfate concentration of less than 20 mg/L (which may indicate that sulfate is reduced to
sulfide at this location).
Methane concentrations were detected in all wells selected for analysis. At two locations (A2-PZ-1 and A2-PZ-2), concentrations were greater than 500 micrograms per liter,
indicative of methanogenic conditions.
ORP measurements for most wells indicate a possible moderately reducing-to-low oxidizing groundwater environment (ranging from 145–46 mV); MW-1, MW-3, PZ-8,
MW-13S, and MW-4 show higher positive ORP values (ranging from 68–121 mV), but
these values are still within the range that may be observed in a reducing environment.
Bear in mind the limitations of ORP field measurements when using ORP data. These
measurements are semi-quantitative and are less reliable redox indicators, since they are
sensitive to interferences from aquifer geochemical conditions (USEPA Region 4, 2009).
2011 ANNUAL GROUNDWATER MONITORING REPORT • FORMER FRENCH ROAD FACILITY, UTICA, NEW YORK PAGE 4-7 Utica 2011 Annual GWM Report (v4)
Field ferrous iron (Fe2+
) measurements conducted in four wells (concentrations ranging
0.01 mg/L in MW-1 to 0.87 mg/L in MW-10) may suggest a mildly reducing environment
in some of these wells. Collecting additional data would be warranted to confirm this.
Geological characterization shows a dark-gray clay lens in the till at most site locations. Gray
clay is typically observed in iron-to-sulfate reducing conditions, as iron oxyhydroxide in the
aquifer sediment is reduced to Fe2+
minerals. The presence of reduced-iron minerals suggests that
the natural-attenuation mechanism for abiotic degradation of chlorinated VOCs may be active at
this site. As demonstrated in many laboratory and field studies reviewed by USEPA
(USEPA, 2009), reactive iron minerals such as iron sulfides, pyrite, magnetite, green rust, and a
number of Fe(II)-containing clay minerals commonly observed in reducing environments may
play a significant role degrading chlorinated solvents through abiotic mechanisms. Taken
together, site geochemical conditions (neutral pH and reducing environment) may be conducive
to the natural degradation of chlorinated VOCs by biotic and abiotic pathways at the study area.
4.7 DATA VALIDATION
Groundwater-sample analyses were performed according to USEPA SW-846 Method 8260B.
Data were reviewed in accordance with the USEPA National Functional Guidelines
(USEPA,1999) and January 2005. Data packages were compiled by a New York State-certified
laboratory and prepared as New York State ―analytical services protocol Category B‖
deliverables. The review was conducted as a ―NYSDEC Tier III evaluation‖ and included a
review of data-package completeness. Field documentation was not included, but the
validation-annotated sampling-result sheets and chain-of-custody documentation were.
Data-usability summary reports were completed in accordance with NYSDEC DER-10
(Technical Guidance for Site Investigation and Remediation [May 2010]).
Data review evaluates data technically, rather than simply determining contract compliance. As
such, the standards against which the data are weighed may differ from those specified in the
contractually stipulated analytical method. The data package is thus presumed to represent the
best efforts of the laboratory, and the data are likewise presumed to have been subjected to
adequate and sufficient quality review before submission. During data review, laboratory
qualified and unqualified data are verified against the supporting documentation. The data
reviewer may add, delete, or modify qualifier codes. The NYSDEC ASP Category-B deliverable
data review includes checks of the following:
2011 ANNUAL GROUNDWATER MONITORING REPORT • FORMER FRENCH ROAD FACILITY, UTICA, NEW YORK PAGE 4-8 Utica 2011 Annual GWM Report (v4)
chain-of-custody forms;
holding times;
GC/MS instrument performance-checks;
instrument calibration;
trip- and/or laboratory (method)-blank detected constituents;
surrogate-spike recoveries;
matrix-spike/matrix-spike-duplicate precision and accuracy;
internal standards;
checking for transcriptions between quantitation reports and laboratory, hard-copy Form ―I‖s; and
blind-duplicate precision.
The data validator performed final validation of data obtained during field sampling and analysis.
Laboratory deliverables were reviewed for accuracy, precision, completeness, and overall data
quality. All laboratory data were reviewed for adherence to method-specific quality
assurance/quality control (QA/QC) guidelines and the data-validation guidelines described above.
Data usability—The review classified the data as valid, usable, or unusable. Valid data are data
for which all QA/QC review criteria have been met and that are acceptable (as per details
outlined in the preceding section). Data were characterized as usable when QA/QC parameters
were marginally outside acceptable limits (e.g., sample holding times had been slightly
exceeded), such that the data may be questionable, but still usable with limitations. Unusable
data are data observed to have gross errors or analytical interference that would render them
invalid for any purpose. Data-usability summary reports were prepared in accordance with
NYSDEC guidance and are included as Appendix G. Data qualifications resulting from
validation are included in the data tables. All data reviewed are considered usable based on the
validation as described above.
